All Swallow greenhouses are now made from Thermowood.
Heat and steam are used to thermally modify the wood to produce an exceptionally strong and durable wood that is perfect for outdoor use.
This process is achieved using natural methods and is non-toxic and chemical free, with one of the many benefits being improved insulation well suited for greenhouses.
After treatment the wood is a beautiful consistent colour that will last far longer than normal treated timber.

The wait was worth it......
Thursday, 16 March 2017  |  Mathew

Fantastic build quality, the shed extension is brilliant, and the attention to detail is first class. The thermowood look and feel makes it look more expensive than it is and certainly competes with some RHS 'certified' versions where you will pay 4 x the price! The large building was erected in less than 4 hours and the guys arrived promptly.

First ever greenhouse
Monday, 26 September 2016  |  Sue

Love it!! Delivery arrived smack on time and had built in 1.5 hours.
My only regret was not ordering a side vent but may go for it at a later date.
Already full of cuttings and seeds

A brilliant greenhouse!
Tuesday, 6 January 2015  |  Bebe

4 weeks in and I absolutely love this greenhouse. It feels really solid and spacious. We used new sleepers as a base and this has given us additional height.
The greenhouse arrived ahead of schedule and on the day the 2 guys arrived, with the greenhouse pre-glazed, promptly at 8am as promised and they were brilliant. By afternoon I had started moving my plants in. Thank you
